1. Dependent on the cooking time: The cooking time for both glutinous rice balls and rice wine are different. Glutinous rice balls take less time to cook, while rice wine takes more time. Thus, if you prefer to have both ready at the same time, start with the rice wine.
2. Prioritize individual preference: Some people might prefer to keep the glutinous rice balls hot or warm after cooking, which can be achieved by starting with rice balls. Conversely, some may want the rice wine to have more time to ferment, making it more authentic in flavor.
3. Time constraints: Another factor that affects the decision of which to prepare first is the available time. If there is not much time available, it is better to go for glutinous rice balls as they require lesser cooking time.
4. Convenience: When preparing both items simultaneously, one that is easier to cook should be prepared first. In this case, glutinous rice balls take less time and effort to prepare.
In conclusion, the choice of which one to cook first entirely depends on personal preference and circumstances. However, it is generally recommended to start with rice wine for those who have a little extra time, so that it can properly ferment before consumption.
